The 30-year-old model and mother has also worked out with a trainer since August and for three weeks leading up to the show, worked out twice daily.

"Everybody is talking about my crazy diet," Lima told E! News on Wednesday. "I know it's very intense but...I just have an athlete's mind and I appreciate doing this thing."

During the Victoria's Secret Fashion Show, models walk the runway in bras, underwear and bikinis, often with very little coverage. They often don feathers or angel wings.

This year, the top lingerie brand's event featured performances from Nicki Minaj, Adam Levine, Jay-Z and Kanye West, while Adriana Lima, Miranda Kerr, Alessandra Ambrosio and other models walked the runway. The 2011 Victoria's Secret Fashion Show airs on CBS on November 29. (See photos from the 2011 Fashion Show).

Last year, Lima wore a $2 million diamond-encrusted bra on the runway and appeared very muscular (Pictured above on the right). At Wednesday's show, she sported black angel wings with a purple and black bustier garter (Pictured above on the left).

"It's not that I do crazy diets throughout the year. I just do it for this particular thing. After this show, I become normal again," Lima continued. "This year, even though my diet was intense, I took it a little bit easier on the working out so I won't be as muscular."

Earlier in the year, Victoria's Secret angel Candice Swanepoel came under fire after being dubbed "too thin" by several news outlets. At an event promoting push-up bikinis, she appeared slimmer than fellow angels Lima and Alessandra Ambrosio.
